The facts
Vodacom Tanzania PLC is a major Tanzanian telecommunications company. Between 2004 and 2009, it took a series of intercompany loans from two related entities: Vodacom Group (the South African parent) and Mirambo (a sister company). Under the loan agreements, Vodacom Tanzania was required to pay interest annually as it fell due.
In practice, Vodacom Tanzania did not pay the interest as it accrued. Payment of interest to Vodacom Group began only in 2015. Payment of interest on the Mirambo loan began in 2009 but withholding tax on that interest was not remitted until 2017. When TRA conducted a tax audit for the years of income 2011 and 2012, it issued a withholding tax certificate of TZS 7,779,581,441 — comprising principal WHT of TZS 6,290,902,580 and late payment interest of TZS 1,488,678,861.
The parties were not in dispute about whether withholding tax was owed on the intercompany interest. The sole issue was timing: did the obligation to withhold and remit arise when the interest accrued (TRA’s position), or only when the interest was actually paid in cash (Vodacom Tanzania’s position)? The answer determined whether the late payment interest penalties of TZS 1.49bn were lawfully imposed.
The litigation
Tax Revenue Appeals Board and Tribunal — taxpayer wins
Both the Board and the Tribunal held in Vodacom Tanzania’s favour. They reasoned that section 82(1) of the ITA is a specific provision dealing with withholding obligations, and that the word ‘pays’ in that section should be given its ordinary meaning: a discharge of liability by actual transfer of funds. On this reading, no withholding obligation arose until Vodacom Tanzania actually made cash payments of interest to its related parties. Since WHT was remitted when payment was made, there was no late payment and no penalties were due.
Court of Appeal — authority wins
The Court of Appeal reversed both decisions on all three grounds of appeal. The reasoning rests on three interlocking propositions:
- Corporations must account on an accrual basis. Section 21(3) ITA is mandatory and unambiguous: ‘a corporation shall account for income tax purposes on an accrual basis.’ Withholding tax is one of the taxes a corporation is obliged to pay. It follows the same principle. The Court found no exception to this rule in section 82(1) — and declined to read one in.
- ‘Payment’ has a technical meaning in the ITA, broader than cash transfer. Section 3 defines ‘payment’ to include the creation of an asset in another person. An ‘asset’ includes a right to income or future income. When Vodacom Tanzania allowed interest to accrue without payment, it was creating an asset (a receivable) in Vodacom Group and Mirambo. That is a ‘payment’ within the technical ITA definition, even though no cash changed hands.
- Section 82(1) does not override the accrual rule. Section 82(1) imposes the withholding obligation; it does not specify the timing basis. The timing is governed by section 21(3). The two provisions are not in conflict and must be read harmoniously. If the legislature had intended an exception, it would have said so explicitly — as it did in the limited exceptions listed in section 82(2).
The Court drew support from a Kenyan Court of Appeal decision which confirmed that ‘payment’ in income tax legislation carries a technical rather than ordinary meaning, and that payment is deemed to occur even when no money changes hands.
ajiho commentary
The accrual trap for deferred intercompany interest
The Vodacom Tanzania case is a textbook illustration of a risk that arises frequently in intragroup financing arrangements in East Africa and more broadly in developing markets: intercompany interest is accrued in accounts but payment is deferred, often for years, because the subsidiary lacks cash or the group prefers to defer settlement. The accrual of interest is recorded. The withholding tax obligation is not.
The Court’s reasoning establishes clearly that in Tanzania, the two obligations move together. Once interest accrues — once the liability is created and the corresponding asset appears on the lender’s books — the withholding tax obligation crystallises. The fact that no cash has been transferred does not matter. A group that defers cash payment while continuing to accrue interest is not deferring its WHT obligation — it is running up a WHT liability with compound late payment interest on top.
For FTTP practitioners, the practical implication is direct: any intercompany loan arrangement in Tanzania where interest is accrued but not paid currently needs to be reviewed for WHT compliance. The risk is not limited to the principal WHT amount — it is amplified by the late payment interest, which in this case represented nearly 24% of the principal assessment.
Regional significance and limits
This ruling is binding in Tanzania. Its persuasive weight beyond Tanzania is limited. The specific outcome depends on section 21(3) of the Tanzanian ITA and the unusually broad definition of ‘payment’ in section 3. Other East African jurisdictions have different legislative frameworks and should be analysed separately.
That said, the underlying tension — between the commercial practice of deferring intercompany payments and tax law’s insistence on accrual accounting — is not unique to Tanzania. Kenya, Uganda, and Rwanda all have accrual-based corporate tax regimes. Groups with intercompany financing arrangements across East Africa should treat this case as a prompt to review their WHT compliance position in each jurisdiction rather than assume that deferral of cash payment defers the tax obligation.
What this means for your business
Groups with Tanzanian subsidiaries borrowing from related parties — whether from a parent, sister company, or group treasury entity — should review whether intercompany interest is being accrued but not currently settled. If it is, a WHT liability is accruing simultaneously. The liability compounds with late payment interest if it is not remitted to TRA as it falls due.
The Seacom case (also in this library) covers related aspects of intercompany financing in Tanzania. The two cases together give a reasonable picture of how TRA approaches intragroup financial transactions and where the principal compliance risks lie.
